Otsalamppu Ansmann HD250RS musta COB LED 4W IP54

The ANSMANN HD250RS is a rechargeable headband flashlight in black with a combined 4W COB LED and 5W Cree LED system, designed for hands-free illumination. It features an integrated 3.7V / 1200 mAh Li‑Po battery rechargeable via Micro‑USB, an adjustable lamp head (up to 45°), a robust ABS housing and an IP54 rating for protection against dust and splashes.

Advantages

The headlamp combines a high-efficiency reflector system and a COB emitter to provide both a long-range focused beam and a wide, homogeneous flood light for close work. At just 52 g it is lightweight and comfortable for extended wear. The elastic, universally adjustable headband includes a multi-function clasp with a hanging hook and an integrated whistle. Two ergonomic pushbuttons and an optional gesture sensor enable simple operation even with gloves on, and the lamp remembers the last brightness setting.

How to use

Charge the integrated Li‑Po battery using a conventional USB power source and the supplied USB to Micro‑USB cable before first use. Select brightness levels with Button 1: combined 100% COB & Cree, 100% Cree, 100% COB, and 30% COB. Use Button 2 to enable or disable the sensor; with the sensor enabled you can switch the lamp on or off by a hand gesture about 10 cm in front of the lamp and cycle brightness via Button 1. Adjust the lamp head angle up to 45° for the required beam direction. The lamp’s controller recalls the last brightness setting when switched on.

Recommendations

For best results, charge the lamp fully before use and select the light mode that matches your task: use the COB mode for wide-area inspection and the Cree LED for long-range illumination. Keep the Micro‑USB port covered from dirt and moisture when not charging to maintain IP54 protection.
